Critics — especially women — are besieged by a brick through the window or Twitter warnings of rape and murder.

As if that were not enough, Unite’s appalling Len McCluskey peddles lies about MI5 agents fomenting civil war.

Corbyn pretends to ride above this by insisting ALL bullying is unacceptable. But he does not lift a finger to stop it.

He may be what Stalinists called a “useful idiot”, someone who has swallowed the revolutionary message without understanding its consequences.

Owen Smith's leadership challenge which will only cement Corbyn into place

I think he knows precisely what is going on and chooses to ignore it.

Labour is disintegrating. Ambitious but unknown Welsh MP Owen Smith is launching a futile leadership challenge which will only cement Corbyn into place.

The vegetarian allotment-tiller will win by a mile, thanks to tens of thousands of recently recruited party members ready to fork out £25 to back their favourite Marxist.

That will leave Westminster MPs with a bleak choice — to toe the socialist line and remain with a party that is doomed to election defeat or to strike out on their own, like the SDP in the Eighties.

The Social Democratic Party split from Labour in the 1980s, but they had giants like former Chancellor Roy Jenkins

As well as David Owen, the youngest-ever Foreign Secretary

But the Gang of Four who led that walkout included giants like , a former Chancellor, Home Secretary and Euro Commissioner, and David Owen, the youngest-ever Foreign Secretary.

Those who remained included big hitters like ex-Chancellor and Defence Secretary Denis Healey.

Even those who helped cause the split — like Corbyn’s hero Tony Benn — had brains and charisma.

There is nobody on either side of the party today with that sort of clout.

Labour is the true Nasty Party

Westminster is abuzz with plans for a coalition between Labour fugitives and Nick Clegg’s Lib-Dem left-overs, the ultimate gesture of despair. Or an alliance with the SNP.

Labour reminds me of the horrifying story about a hot air balloon which broke its moorings. Half a dozen helpers tried to hold it down and were 50 feet above the ground before they realised it was too late to let go.

Whichever way they jump now, they are in peril. Those who stay risk annihilation at the next election. Those who defect will almost certainly be dumped by their constituency parties.

Rumours abound of a coalition between Labour fugitives and Nick Clegg’s Lib-Dem left-overs

Could they do a deal with Ukip? Not likely. Do they stay together and launch a new Independent Labour Party, a brave and uncertain gamble?

Robert Harris, author of the best-selling Dictator, likens the UK today to Thirties Germany and the rise of the Nazis.

Confusingly, he compares Hitler’s use of referendums to bypass parliamentary democracy with the recent EU referendum and the Tories.

Hitler rose to power with the National Socialist Party. And there have been times when Communists hoped to bring totalitarian rule to Britain.

If we are looking for a parallel, it comes not from the Tory Right but from Jeremy Corbyn’s anti-Semitic pro- revolutionary Loony Left.

An allegiance with Nicola Sturgeon's SDP is also being floated as a possibility

Labour, not the Tories, is the true Nasty Party.

In the circumstances, we are very lucky to have Theresa May as Prime Minister.

Shadow Chancellor John McDonnell, Corbyn’s thuggish puppet-master, yesterday used BBC cameras to dismiss the bullies as a “small group” who wanted to discredit the leader.

It was like watching a backstreet hoodie trying to persuade a frail old lady his foam-flecked Staffie was “only being friendly”.

Pray for Hillary Clinton

Trump's nomination is still hard to fathom

CONFIRMATION of “The Donald” as Republican candidate for the Presidency is a real shocker.

Along with millions of Americans, including her own fellow Democrats, I am no fan of Hillary Clinton.

But while she may be corrupt, deceitful and blinded by ambition, I don’t think she’s quite bonkers.

Let us hope Hillary Clinton beats him to the White House

It’s hard to say the same for pouting, posing comb-over king Donald Trump.

Why should we believe a delusional, Mafia-hugging, misogynist egomaniac has what it takes to be the leader of the world’s greatest superpower?
